Specification of Letters Patent.

Application filed May 15, 1911.

Patented Nov. 28, 1911.

Serial No. 627,291.

To all whom it may concern:

Be it known that I, EMMA E. WILLS, a

' citizen of the United States, residing at Chetopa, in the county ofLabette and State of Kansas, have invented certain new and usefulImprovements in Egg-Testers, of which the following is a specification.

This invention relates to the art of incubation, and comprisesessentially a novel form of device for testing the fertility of eggs.

The invention comprises particularly a sight-tube adapted to be fittedto the head of the person, and through which he may examine the egg inprocess of incubation, the tube or body of the testing device beingpreferably made of flexible material not only to cheapen the same but toenable it to be collapsed to economize space in transportation, specialmeans being provided for causing the portion of the tube fitting againstthe head to conform with the shape of the latter.

The invention resides also in' other specific features of construction,the form and advantages of which will be presented more fullyhereinafter.

For a full understanding of the present invention, reference is to behad to the following description and to the accompanying drawings, inwhich Figure 1 is a perspective view of a testing device embodying theinvention; Fig. 2 is a vertical longitudinal sectional view of the same;Fig. 3 is a view showing the device collapsed as when out of use.

Throughout the following detail description and on the several figuresof the drawings, similar parts are referred to by like referencecharacters.

The present invention affords an exceedingly simple, cheap andadvantageous device for the purpose for which it is de-v signed, thetester being composed primarily of a sight-tube or body 1, made offabric or flexible material and tapering toward one end. At the largerend, the sight-tube 1 is cut away at its upper and lower portions toform curved seats 2 conforming with the shape of the head of a personusing the device, and head straps 3 of elastic are provided.

The end portions of the tube or body 1 along the seats 2 are reinforcedpeculiarly by means of a flexible Wire strand, or similar part 5, theobject in employing the latter being to enable the user of the device toshape the lower portion of the member 1 at the lower seat 2 in such away that said portion will conform with the shape of the nose to causethe end of the tube fitting against the head to rest in close contacttherewith, excluding all light or rays which would interfere withquickly and readily determining the fertility of the egg under test. Bymanipulating the flexible reinforcement 5 so as to bend the sameproperly, the shape 1 or curvature of the larger end of the tube 1 maybe altered and such shape retained until further manipulation.

A suitable binder 6 is preferably provided at the larger end of the body1 and a similar' binding strip 7 is employed at the smaller end adjacentto which is also located the egg rest 8 in the form of a small curvedbasket on which the egg is supported while held in the hand and pressedagainst the open smaller end of the device.

The rest 8 is preferably of concave form and may be pivotally connectedat 9, near the side portions thereof, to the small end of thesight-tube 1. A small retaining catch 10 secured to the smaller end ofthe tube 1 will hold the rest 8 in its operative position when thedevice is in use but may be disengaged from the rest to permit thelatter to be folded into the tube 1 preparatory to collapsing the sameafter use.

Located in the tube 1 intermediate the ends thereof is a magnifying lens11 detachably held in place by small spring catches 12, a plurality ofwhich are secured by rivets or other fastenings to the inner wall of thetube. The ends of the catches 12 facing the larger end of the tube arefree and yieldable outwardly by reason of the flexibility of the tube 1so as to permit the lens 11 to be readily removed or placed in positionaccording to the desire of the user of the contrivance.

The flexibility of the body or tube 1 of the testing device, and thedetachability of the lens 11 permit the device to be collapsed into asubstantially flat position, whereby space is economized for sending thedevice in the mails, or otherwise.

Having thus described the invention, what is claimed as new is:

1. An egg tester comprising a flexible tapering tubular body, headattaching means at the larger end of the body for securing the device tothe person, and a rest pro jecting from the lower portion of the smallerend of the body adapted to be folded into the body preliminary tocollapsing of the latter.

2. An egg tester comprising a flexible tapering tubular body, headattaching means at the larger end of the body for securing the device tothe person, a rest projecting from the lower portion of the smaller endof the body adapted to be folded into the body preliminary to collapsingof the latter, and a detachable lens fitted in the body intermediate itsends.

3. An egg tester consisting of a flexible tapering tubular body, headattaching means at the larger end of the body for securing the device to[the person, a rest projecting from the lower portion of the smaller endvof the body adapted to be folded into the body preliminary tocollapsing of the latter,

and a catch for normally holding "the rest in an operative position, alens fitted in the body intermediate the ends of the same, and catchesholding said lens in anoperative position and yieldable by reason of theflexibility of the body to release the lens.

4. An egg tester consisting of a flexible tapering tubular body, headattaching means at the larger end of the body, a lens fitted in the bodyintermediate the ends of the latter, and catches holding said lens inoperative position and yieldable by reason of the flexibility the lens.

In testimony whereof I afliX my signature in presence of two Witnesses.
